Abstract: A textured surface of oil and gas equipment includes a first substrate, an antiwear coating, and a second substrate, and further includes a texture, where the texture includes a first texture and/or a second texture; the first substrate and the second substrate are capable of moving relative to each other when operating, the first texture is arranged on a surface of the first substrate that is in contact with the antiwear coating, the second texture is arranged on a surface of the antiwear coating that is in contact with the second substrate. A method for machining the textured surface of oil and gas equipment is provided, which improves various performances of the oil and gas equipment such as antifriction, wear resistance, and corrosion resistance by combining a coating with a texture, so as to prolong the service life of the oil and gas equipment, increase oil and gas production efficiency.

Abstract: In a cleaning system and method for a vehicle interior, the system includes a floor cleaning device, at least one sensor, a seat lifting device, and a controller. The floor cleaning device is configured to be pulled out from the storage space to clean the floor of a vehicle, at least one sensor detects a driving state of the vehicle and output corresponding state information, the seat lifting device raises and lowers at least a front seat of the vehicle, and the controller determines whether the vehicle is in a parked state according to the state information, controls, if the vehicle is in a parked state, the seat lifting device to raise the at least a front seat of the vehicle and simultaneously controls the floor cleaning device to be drawn out from the storage space to clean the floor of the vehicle.
